Methods and systems for providing personalized content based on shared listening sessions

ABSTRACT

An electronic device receives a request, from a first device of a host user, to initiate a first shared playback session for the first device and one or more additional devices. The electronic device streams media content from a first playback queue to the first device and to the one or more additional devices, the first playback queue including one or more media content items corresponding to the first shared playback session. The electronic device determines that the first device of the host user has left the first shared playback session and, in response, maintains the first playback queue to be accessed by the one or more additional devices. After the host user has left the first shared playback session, the electronic device provides one or more media content items from the first playback queue to at least one of the one or more additional devices.

RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 16/784,090, filed Feb. 6, 2020, entitled “Methods and Systems for Providing Personalized Content Based on Shared Listening Sessions,” which claims priority to U.S. Prov. Patent App. 62/806,244, filed Feb. 15, 2019, all of which are hereby incorporated by reference in their entirety.

TECHNICAL FIELD

The disclosed embodiments relate generally to media playback, and, in particular, providing shared media playback sessions.

BACKGROUND

Access to electronic media, such as music and video content, has expanded dramatically over time. As a departure from physical media, media content providers stream media to electronic devices across wireless networks, improving the convenience with which users can digest and experience such content.

As part of the service they provide and to assist users in discovering new content, media content providers track and process user data in an attempt to understand user preferences, and ultimately to provide relevant content to users.

SUMMARY

Streaming media content to many electronic devices associated with many different users creates an opportunity to allow multiple users to have a shared media content experience. For example, a shared user experience allows each member within a group of users to contribute to and control a collection of media content. In this way, a plurality of users is enabled to access, contribute to, and control playback of media content items.

A user participating in a shared media content session may wish to limit or control the extent to which content not selected by the user influences the listening history of the user and content suggestions provided to the user. Accordingly, there is a need for systems and methods for personalizing media content based at least in part on the sources of media content selection during a shared media experience. By identifying the sources of media items that are consumed by a user, content providers are able to determine whether media items have been selected by the user or by another party, and how these selections should affect the user's personal listening profile. The user's personal listening profile is then used to generate personalized recommendations for the user. The content provider is therefore better able to personalize content by distinguishing between media items that the user selected and media items that the user did not select.

In accordance with some embodiments, a method is performed at an electronic device (e.g., associated with a media content provider) having one or more processors and memory storing instructions for execution by the one or more processors. The electronic device is associated with a media-providing service. The method includes storing, for a first user of the media-providing service, a listening history corresponding to media content items provided by the media-providing service that have been previously consumed by the first user. The method further includes providing a shared playback queue to a first device of the first user and a second device of a second user, the shared playback queue including one or more media content items corresponding to a shared playback session. The method further includes identifying a source of a first media content item of the one or more media content items in the shared playback queue. The method includes, based on the identified source of the first media content item in the shared playback queue, determining whether to include the first media content item in the listening history of the first user. The method includes providing information for a second media content item to the first device of the first user based on the listening history of the first user.

In accordance with some embodiments, an electronic device (e.g., a server system, a client device, etc.) includes one or more processors and memory storing one or more programs configured to be executed by the one or more processors. The one or more programs include instructions for performing the operations of the method described above. In accordance with some embodiments, a computer-readable storage medium has stored therein instructions that, when executed by an electronic device, cause the server system to perform the operations of the method described above.

Providing personalized content directly to the device of a user, without requiring user input to generate a set of content for playback, reduces and/or eliminates user navigation through a series of user interfaces (e.g., user interfaces indicating content associated with various content creators) for the purpose of content selection and organization. Reducing user input to navigate a series of user interfaces for assembling a set of content for playback reduces the extent to which user interface data and user input data is transmitted between devices in a media content system and reduces the processing power and power consumption required for providing content to users, thereby improving the functioning of the devices. Further, distinguishing between sources of the media content and selectively storing content items that have been selected by a predefined source reduces the amount of memory used to store listening history information for a user.

FIG. 1 is a block diagram illustrating a media content delivery system 100 in accordance with some embodiments. The media content delivery system 100 includes one or more client devices 102 (e.g., client device 102-1 to client device 102-m, where m is an integer greater than one), one or more media content servers 104, and one or more media presentation systems 108, including speaker 108-1, television (TV) 108-2, digital versatile disk (DVD) player 108-3, and/or other media presentation system 108-n (where n is an integer greater than three). The one or more media content servers 104 are associated with (e.g., at least partially compose) a media-providing service. One or more networks 112 communicably couple the components of the media content delivery system 100. In some embodiments, the one or more networks 112 include public communication networks, private communication networks, or a combination of both public and private communication networks. For example, the one or more networks 112 can be any network (or combination of networks) such as the Internet, other wide area networks (WAN), local area networks (LAN), virtual private networks (VPN), metropolitan area networks (MAN), peer-to-peer networks, and/or ad-hoc connections.

In some embodiments, a client device 102-1, 102-2, or 102-m is associated with one or more users. In some embodiments, a client device 102 is a personal computer, mobile electronic device, wearable computing device, laptop computer, tablet computer, mobile phone, feature phone, smart phone, digital media player, or any other electronic device capable of presenting media content (e.g., audio and/or video). A client device 102 connects to a media presentation system 108 wirelessly or through a wired connection (e.g., directly through an interface, such as an HDMI interface). In some embodiments, a client device 102 is a headless client. In some embodiments, client devices 102-1 and 102-m are the same type of device (e.g., client device 102-1 and client device 102-m are both mobile devices). Alternatively, client device 102-1 and client device 102-m are different types of devices.

In some embodiments, client devices 102-1, 102-2, and 102-m send and receive media-control information through the networks 112. For example, client devices 102-1, 102-2, and 102-m send media control requests (e.g., requests to play music, movies, videos, or other media items, or playlists thereof) to media content server 104 through network(s) 112. In some embodiments, client devices 102-1, 102-2, and 102-m, receive authentication tokens from the media content server 104 through network(s) 112.

In some embodiments, client device 102-1 communicates directly (e.g., through a wired and/or wireless connection) with client devices 102-2 and/or 102-m. For example, in some embodiments client devices 102 directly communicate playback commands and/or audio code signals between each other (e.g., the media content server 104 may or may not be involved in the exchange). In some embodiments, client device 102-2 communicates directly with client device 102-m. In some embodiments, client device 102-1 communicates directly with media presentation systems 108. As pictured in FIG. 1, client device 102-1 is able to communicate directly (e.g., through a wired and/or wireless connection) with media presentation systems 108, while client device 102-m communicates with the media presentation systems 108 through network(s) 112. In some embodiments, client device 102-1 uses the direct connection with media presentation systems 108 to stream content (e.g., data for media items) for playback on the media presentation systems 108.

In some embodiments, client device 102-1, client device 102-2 and client device 102-m each include a media application 422 (FIG. 4) that allows a user of the client device to browse, request (e.g., for playback at the client device 102 and/or a media presentation system 108), and/or present media content (e.g., control playback of music tracks, videos, etc.). Media content may be stored locally (e.g., in memory 412 of the client device 102, FIG. 4) and/or received in a data stream (e.g., from the media content server 104). The media presentation system 108 may be part of the client device 102, such as built-in speakers and/or a display, or may be separate from the client device 102, such as a wirelessly coupled speaker (e.g., speaker 108-1).

In some embodiments, client device 102-1 and client device 102-2 each include an instance of shared playback queue 103-1 (e.g., within media application 422). In some embodiments, shared playback queue 103-1 includes a set (e.g., an ordered list, such as a playlist) of media content items provided by the media content server 104. For example, the media content server 104 establishes a shared playback session (e.g., for two or more client devices of two or more users), stores a shared playback queue corresponding to the shared playback session, and/or provides the shared playback queue to the two or more client devices (e.g., client device 102-1 and client device 102-2). In some embodiments, the two or more client devices 120 are enabled to view and/or edit (e.g., add, remove, and/or reorder) content in the shared playback queue. For example, client device 102-1 and client device 102-2 are each provided with at least a portion of the same shared playback queue 103-1. In some embodiments, the shared playback queue 103-1 includes media content items selected by any combination of client device 102-1, client device 102-2, any other client device(s) 102, presentation systems 108, and/or the media content server 104. In some embodiments, the media content items from the shared playback queue are streamed to (e.g., played at and/or provided to) one or more of media presentation systems 108. For example, each client device 102-1 and client device 102-2 accesses (e.g., views, edits (adds and/or removes media content items from), and/or controls presentation of) the shared playback queue 103-1 while the shared playback queue is presented at one or more of media presentation systems 108. Co-located users are enabled to access the shared playback queue 103-1 on individual devices while streaming media content through media presentation system 108. In some embodiments, the media content items from the shared playback queue are streamed to each of the client devices 102-1 and 102-2 (e.g., instead of or in addition to media presentation system 108). It is to be understood that the shared playback queue 103-1 is enabled to be shared on additional client devices 102 in addition to client device 102-1 and client device 102-2. In some embodiments, a shared playback queue 103-x (distinct from shared playback queue 103-1) is shared between a plurality of client devices 102 (including client device 102-m). For example, the media content server 104 provides a plurality of shared playback queues 103-1 through 103-x, where the shared playback queue 103-1 is provided to a first subset of client devices 102 (e.g., client devices 102-1 and 102-2) and the shared playback queue 103-x is provided to a second subset of client devices 102 (e.g., including client device 102-m) (e.g., distinct from the first subset).

In some embodiments, the media content server 104 stores and provides media content (also referred to as media items) (e.g., media content requested by the media application 422 of client device 102-1, 102-2, and/or 102-m, and/or the shared playback queue 103-1) to client devices 102 and/or media presentation systems 108 via the network(s) 112. Content stored and served by the media content server 104, in some embodiments, includes any appropriate content, including audio (e.g., music, spoken word, podcasts, etc.), videos (e.g., short-form videos, music videos, television shows, movies, clips, previews, etc.), text (e.g., articles, blog posts, emails, etc.), images (e.g., photographs, drawings, renderings, etc.), games (e.g., 2- or 3-dimensional graphics-based computer games, etc.), or any combination of content types (e.g., web pages that include any combination of the foregoing types of content or other content not explicitly listed). Audio media items (i.e., audio items) may be referred to as tracks. The description of the media content server 104 as a “server” is intended as a functional description of the devices, systems, processor cores, and/or other components that provide the functionality attributed to the media content server 104. It will be understood that the media content server 104 may be a single server computer, or may be multiple server computers. Moreover, the media content server 104 may be coupled to other servers and/or server systems, or other devices, such as other client devices, databases, content delivery networks (e.g., peer-to-peer networks), network caches, and the like. In some embodiments, the media content server 104 is implemented by multiple computing devices working together to perform the actions of a server system (e.g., cloud computing).

As described above, media presentation systems 108 (e.g., speaker 108-1, TV 108-2, DVD 108-3, media presentation system 108-n) are capable of receiving media content (e.g., from the media content server 104) and presenting the received media content. For example, speaker 108-1 may be a component of a network-connected audio/video system (e.g., a home entertainment system, a radio/alarm clock with a digital display, or an infotainment system of a vehicle). In some embodiments, the media content server 104 sends media content to the media presentation systems 108. For example, media presentation systems 108 include computers, dedicated media players, network-connected stereo and/or speaker systems, network-connected vehicle media systems, network-connected televisions, network-connected DVD players, and universal serial bus (USB) devices used to provide a playback device with network connectivity, and the like.

FIG. 2A illustrates a graphical user interface 210-1 displayed by a display of a client device 102-1 associated with a user (e.g., Sara). The graphical user interface 210-1 illustrated in FIG. 2A represents a first sharing interface from a host user's (e.g., Sara's) perspective. In some embodiments, the graphical user interface on device 102-1 includes a device selection portion 202-1. The device selection portion 202-1 includes user interface objects that correspond to one or more presentation devices, such as “This Phone” 203-1, “Living Room” 204-1, and “More devices” 205-1. In some embodiments, the device 102-1 receives a user input at a location that corresponds to a presentation device user interface object in the device selection portion 202-1 to select a presentation device for presentation of the media content (e.g., received by device 102-1 from media-providing server 104). For example, the device receives a user input (e.g., from Sara) at a location corresponding to the displayed user interface object labeled “This Phone” 203-1 to select client device 102-1 as the presentation device. In this manner, client device 102-1 is selected as the playback device for a shared playback queue to which multiple client devices 102 are able to contribute.

In some embodiments, the graphical user interface 210-1 displayed by device 102-1 (and graphical user interface 210-2 displayed by device 102-2) includes a volume control for controlling the playback volume of the selected presentation device.

The first sharing interface 210-1 from the host user's perspective allows the host to initiate a shared playback session (e.g., using the Connect with friends portion of the interface). The shared playback session allows each of the participating users (e.g., the host user and the participants) to access a shared playback queue associated with the playback session. For example, a single shared playback queue is presented to all users of the shared playback session. In some embodiments, the shared playback queue corresponds to a playlist that includes media content items to be presented (e.g., at the selected presentation device). The users are able to access the queue and/or leave the queue.

In some embodiments, to initiate the shared playback session, the client device 102-1 displays a code 206 that can be scanned by a camera or sensor of a second client device (e.g., device 102-2). For example, code 206 is a machine-readable code as described in U.S. Pat. No. 10,133,947, hereby incorporated by reference in its entirety. In some embodiments, code 206 is an image including a row of bars of varying lengths, a bar code, a QR code, or another optical code. The graphical user interface 210-1 displayed by client device 102-1 includes a user-selectable affordance “Scan Code” 208, which, when selected, initiates a mode in which device 102-1 is enabled to scan a code (e.g., using a camera of device 102-1) presented on another user's device (e.g., to join as a participant instead of as a host). For example, the client device 102-1 has the option to either host the shared playback session (e.g., by having another user scan the code 206) or to be a participant in another user's shared playback session (e.g., by selecting “Scan Code” 208 and then scanning a code displayed on another user's device).

FIG. 2B illustrates a graphical user interface 210-2 displayed by client device 102-2 associated with a second user (e.g., David). In some embodiments, graphical user interface 210-1 and graphical user interface 210-2 are generated by a program associated with a media content provider (e.g., media application 422, user interface module 420, and/or a module executed by media content server that transmits graphical user interface data to one or more client devices). In some embodiments, graphical user interfaces 210-3 (FIG. 2C), 210-4 (FIG. 2D), 221-1 (FIG. 2E), and/or 221-2 (FIGS. 2F, 2H, 2I and 2J) are generated by the same software.

Graphical user interface 210-2 is displayed after the client device 102-2 has scanned a code to join a shared playback session that was displayed on another device. For example, David (using client device 102-2) scans Sara's code 206 (displayed on Sara's device 102-1). In response to scanning Sara's code 206, David has joined a shared playback session with Sara. In some embodiments, Sara is designated to be the host of the shared playback session because Sara's code 206 was used to initiate the shared playback session. In some embodiments, a server system initiates (e.g., establishes) the shared playback session in response to receiving an indication that a first user's code has been scanned by another user of the media-providing service.

In some embodiments, a first subset of controls for playback of the shared queue are only available to the host and a second subset of controls for playback of the shared queue are available to all members of the shared playback session. As shown in FIG. 2B, graphical user interface 210-2 includes a device selection portion 202-2. In some embodiments, when client device 102-1 is the host device of a shared playback session, client device 102-2 is not enabled to select a presentation device. For example, only the host device of the shared playback session is enabled to select a presentation device for presenting content of the shared playback queue 103 and participants of the shared playback session are not enabled to change the device at which media content is played back. In some embodiments, graphical user interface 210-2 displayed on client device 102-2 includes user interface objects that correspond to one or more presentation devices, such as “Sara's Phone” 203-2, “Living Room” 204-2, and “More devices” 205-2. In some embodiments, the one or more presentation devices indicated in device selection portion 202-2 on graphical user interface 210-2 correspond to the one or more presentation devices indicated in device selection portion 202-1 on graphical user interface 210-1. In some embodiments, the user interface objects 203-2, 204-2 and 205-2 are non-selectable user interface objects (e.g., as indicated by the shading of the user interface objects). In some embodiments, the user of client device 102-2 is not enabled to select the presentation device (e.g., only the host device is enabled to select the presentation device). In some embodiments, a volume control is displayed to all members (e.g., the host and all participants) of a shared playback session, enabling any of the users in the shared playback session to control the loudness of media playback by the presentation device.

In the illustrative example of FIG. 2B, before joining the shared playback session, client device 102-2 (e.g., David's device) was consuming (e.g., listening to) media content (e.g., from David's personal listening queue/music library). For example, the media-providing service was streaming media content from David's personal queue to David at device 102-2. In response to David's device 102-2 scanning code 206 displayed by Sara's device 102-1, the media-providing service stops streaming media content from David's personal queue to device 102-2, and initiates playback of the media content included in a shared playback queue associated with the shared playback session at the presentation device selected by the host (e.g., Sara). In some embodiments, the media-providing service streams the shared playback queue to David's device 102-2 in addition to playback device 102-1.

Client device 102-2 further indicates the user(s) that are connected to the shared playback session in a shared playback session user listing portion 212 (labeled “You're connected to”) of the graphical user interface. The shared playback session user listing portion 212 indicates identifying information of users that have joined the shared playback session. Identifying information for the user (e.g., owner) of the device that displays the shared playback session user listing (e.g., “David”) may or may not be displayed in the listing. The graphical user interface 210-2 also has a user-selectable affordance to “Leave” 214 the shared playback session. In some embodiments, in response to activation of “Leave” at a device, the device disconnects from the shared playback session.

In some embodiments, after client device 102-2 has joined the shared playback session, the client device 102-2 displays code 206 for the shared playback session that includes client device 102-1 and 102-2 (e.g., the same code 206 is displayed on device 102-1 and device 102-2). Another client device is enabled to join the shared playback session by scanning the code 206 on either client device 102-1 or 102-2 (e.g., every user in the session is enabled to display a code to allow additional users to join the session).

In some embodiments, the code 206 expires after a predefined amount of time. In some embodiments, at the end of the shared playback session, the code 206 ceases to be displayed. In some embodiments, when code 206 ceases to be displayed, a new code (corresponding to a second shared playback session) is displayed. For example, the code 206 is uniquely associated with the shared playback session (e.g., each playback session has its own code). In some embodiments, alternative sharing methods are used in lieu of or in addition to displaying a scannable code. For example, a shared playback session is established via:

-   -   playback, by a first (host) device of an audio code that is         detectable by a second device,     -   A PIN (e.g., a four (or other integer) digit (numeric and/or         alphanumeric) code displayed to the host device) that can be         input at a second device,     -   A determination of geographic co-location (e.g., in accordance         with a determination that a second device comes within a         predetermined distance of a first (host) device),     -   A link (e.g., a universal resource locator) transmitted from the         first client device to the second client device (e.g., directly         transmitted between client devices or forwarded via media         content server 104), and/or     -   a determination that the client devices are connected to a same         wireless network (e.g., Wi-Fi).

In some embodiments, the code is assigned to the session by the server system of the media-providing service.

FIGS. 2C-2D illustrate examples of client devices 102-1 and 102-2 using an audio code (e.g., instead of a scannable code 206) to establish and/or connect to the shared playback session. For example, FIG. 2C displays a graphical user interface 210-3 that includes an affordance labeled “Play Audio Code” 218, which, when selected (e.g., by user input 222) causes the client device 102-1 to output an audio signal that corresponds to audio code 216. Audio code 216 is an audio item (e.g., audible range, ultrasonic, and/or infrasonic) that uses one or more audio characteristics (e.g., frequency, duration, amplitude, combinations of tones, and/or variations thereof over time) to identify (e.g., uniquely identify) a shared listening session. In some embodiments one or more speakers of client device 102-1 output an audio code. The client device 102-2 receives audio code 216 using one or more microphones of the client device. Upon receiving audio code 216, client device 102-2 (and/or client device 102-1) transmits information associated with audio code 216 (e.g., the audio code or information generated based on the received audio code) to the media server 104. In response to receiving the information associated with the audio code, the media server causes the shared playback session that is associated with the audio code from client device 102-1 to be joined by client device 102-2.

In some embodiments, the graphical user interface 210-3 displayed by client device 102-1 includes an affordance 220 (labeled “Other Sharing Options”) that, when selected, causes a list of options for establishing and/or connecting to the shared playback session to be displayed. In some embodiments, the user selects, from the list of options, a method of connecting to the shared playback session.

FIG. 2D illustrates a graphical user interface 210-4 displayed on client device 102-2 after joining the shared playback session hosted by client device 102-1. For example, client device 102-2 received the audio code 216 output by client device 102-1, and, in response to receiving the audio code 216, joined the shared playback session. In some embodiments, in response to receiving audio code 216, client device 102-1 displays, on graphical user interface 210-4, affordance 218, that, when selected causes client device 102-2 to output the audio code 216 to allow additional users to join via the audio code 216.

FIGS. 2E and 2F illustrate graphical user interfaces 221-1 and 221-1 presented on client device 102-1 and client device 102-2, respectively, during the shared playback session. Both client devices 102-1 and 102-2 include information regarding the currently presented media content in Playing From Playlist portion 224. In some embodiments, the information includes metadata of the media content that is being presented at the presentation device. For example, the information includes cover art image 224-1 as well as a title and/or artist information 224-2 (e.g., “Track 1,” “Artist 1”) of the media content item. The information also includes context data regarding the playback of the media content. For example, media scrubber control 226 (e.g., including a playhead that indicates a current playback point in a media item and that, when dragged across a timeline, changes the point in time from which the media item is played back) is presented on the client device. The graphical user interfaces 221-1 and 221-2 also include a connection indication 228, which indicates how many additional users and/or devices are connected to the shared playback session. In some embodiments, the client device 102-1 detects an input at a location that corresponds to connection indication 228. In response to detecting the input at the location that corresponds to connection indication 228, device 102-1 displays a sharing user interface (shown in FIG. 2B).

In some embodiments, one or more controls 230 displayed by client device 102-1 are the same as controls 230 displayed by client device 102-2. While the shared playback session is active, users that have joined the session are able to access the shared queue, and leave the queue. For example, any user is enabled to select to operate skip back 230-2 control to cease playback of the current media content and initiate playback of the prior track, pause (or play) 230-3 control to temporarily stop playback of the currently presented media content item (or resume playback), skip forward 230-4 control to begin playback of a next media content item in the shared playback queue, or shuffle 230-5 control to present the media content items of the shared playback queue out of order (e.g., the order presented as a list). In some embodiments, controls 230 are displayed to only a subset of users (e.g., as selected by the host) in the shared playback session. In some embodiments, the server 104 transmits controls 230 only to the host device (e.g., Sara's device 102-1), and the other users (e.g., client device 102-2) cannot use controls 230 to control playback. In some embodiments, the server transmits (e.g., for display) controls 230 to the devices of other users, but the controls are not selectable by the other users. In some embodiments, a first portion of controls 230 are transmitted, from the server 104, to the host and participants, and a second portion of controls 230 are only transmitted to the host. In some embodiments, at least one control displayed to a user, when operated, affects information stored in association with the user's profile (and does not affect the experience of other users in the shared playback session). For example, the favorite control 230-1 (which, when activated, adds the currently playing media content item to a favorites list and/or to the device's locally stored library) is displayed at device 102-1, while a distinct favorite control 230-6 is displayed at to device 102-2. This way, participants cannot add one or more media content item's to the host's favorites list. Instead, each device (e.g., participant) is enabled to activate the favorite control for the respective user of the device (e.g., each participant has a separate and distinct favorites list). In some embodiments, the favorite control is deactivated for participants (e.g., only the host is enabled to add to the host's favorite list during the shared playback session).

In some embodiments, only a host device of the shared playback session is enabled to control settings of the shared playback session. For example, the server transmits, to a host device, controls for removing and/or blocking participants from joining the shared playback session. In some embodiments, the server transmits, only to the host device, controls to change a presentation device and/or settings of the presentation device (e.g., volume).

FIG. 2G illustrates a user input 232 detected by client device 102-1 (Sara's device) at a location corresponding to the “Leave” affordance 214. In some embodiments, because Sara is the host of the shared playback session, in response to receiving (e.g., at the server 104 and/or at client device 102-1) an indication of an input at the “Leave” affordance 214, the shared playback session ends.

In some embodiments, a client device 102-m joins the shared playback session hosted by client device 102-1 (e.g., Sara) after client device 102-2 (e.g., David) has joined the shared playback session. In some embodiments, when an indication of an input at the “Leave” affordance is received from a participant (e.g., not the host), on a respective participant client device, the shared playback session continues and the playback queue continues to be presented to the remaining users (e.g., the host and the remaining participants). For example, in response to receiving an indication of an input at the “Leave” affordance at client device 102-2 (e.g., David), client device 102-2 leaves the shared playback session (and is no longer connected to Sara and device 102-m). Because David was a participant (e.g., not the host) of the shared playback session, the shared playback queue continues to be presented to client device 102-1 (e.g., Sara) and client device 102-m. In some embodiments, after David has left the shared playback session, the device (e.g., server and/or device 102-m) receives an indication of an input at device 102-m to activate the “Leave” affordance. In some embodiments, in response to the input at device 102-m to “Leave,” the shared playback session continues on host device 102-1 even though there are no additional participants. In some embodiments, in response to the input at participant device 102-m to “Leave,” the shared playback session is terminated (e.g., by the server 104 and/or host device 102-1) because only host device 102-1 remained in the shared playback session.

In some embodiments, in response to the host leaving the shared playback session, the server system terminates the shared playback session and provides the users that remained in the shared playback session (e.g., user of device 102-2) with a notification 234 that the shared playback session is over, as illustrated in FIG. 2H. In some embodiments, the user of device 102-2 is enabled to dismiss the notification by selecting acknowledgement (“Got It”) affordance 236. In some embodiments, after the shared playback session has been terminated (e.g., by the server system), the user of client device 102-2 chooses to continue to listen to the media content items that were included in the shared playback queue. For example, as shown in FIG. 2I, the user continues to listen to Track 1 from “Session 1”. In some embodiments, because the playback queue of session 1 is maintained on client device 102-2, client device 102-2 is enabled to initiate a second shared playback session that includes the playback queue of the shared playback session that was terminated. In some embodiments, the playback queue of session 1 is maintained on the media content server 104 (e.g., in addition to or instead of being stored on the client device). This way, any remaining users who want to continue consuming the shared playback queue after the host terminated the session are able to join a new (second) shared playback session that continues from the point in the queue at which the previous session ended. After the shared playback session is terminated, connection indication 228 (FIG. 2F) no longer indicates that other devices are connected to device 102-2 through a shared playback session. Client device 102-2 displays connection options 240 to, for example, allow the user of device 102-2 to connect to or change a presentation device.

As shown in FIG. 2J, in some embodiments, in accordance with a termination that host device 102-1 has terminated the shared playback session, client device 102-2 ceases playback of the shared playback queue and initiates playback of the previously playing personal queue of the user of client device 102-2 (e.g., at a point in the personal queue that was playing when the user of device 102-2 joined the shared playback queue). For example, client device 102-2 is now playing “Track 2” indicated by information 224-3 and 224-4 from “Today's Top Hits” instead of continuing to play “Track 1” of the shared playback queue. In some embodiments, in response to the client device 102-2 selecting to return to the personal queue of the user, the previously shared playback queue (e.g., from Session 1) is released from storage (e.g., the shared playback queue for the shared playback session that had been terminated is cleared). In some embodiments, the client device resumes a previous personal queue that was streamed at the client device (e.g., David will resume listening to what was playing before joining Sara's shared playback session).

FIGS. 3A-3B are flow diagrams illustrating a method 300 for providing personalized content to a user, in accordance with some embodiments. Method 300 may be performed (302) at an electronic device (e.g., media content server 104, FIGS. 1 and 5; client device 102, FIGS. 1 and 4) having one or more processors and memory storing instructions for execution by the one or more processors. The electronic device is associated with a media-providing service (e.g., provides media content for playback to client devices 102 and/or media presentation systems 108 in a media content delivery system 100, and/or executes an application for the media-providing service). In some embodiments, the method 300 is performed by executing instructions stored in the memory of a server system (e.g., in memory 506, FIG. 5) or client device (e.g., in memory 412, FIG. 4). In some embodiments, the method 300 is performed by a combination of the server system and a client device.

Referring now to FIG. 3A, in performing the method 300, the electronic device stores (304), for a first user (e.g., David) of the media-providing service, a listening history corresponding to media content items provided by the media-providing service that have been previously consumed by the first user. In some embodiments, the listening history of the first user includes (306) content items selected by the first user for a playback queue (e.g., an individual playback queue that is distinct from the shared playback queue) of the first user.

In some embodiments, a media-providing service examines a user's listening history to attempt to identify user habits and personalize content based on these habits. For example, the listening history includes information about previous media content the user has consumed from the media-providing service, such as a title of a media content item, an artist, a genre of the media content item, etc. In some embodiments, the listening history of the user also includes contextual information about when the user consumed the media content items (e.g., a time of day, a day of the week, etc.). The media content server 104 collects the listening histories for multiple users (e.g., server system 104 stores listening history of the user in the listening history module 526, FIG. 5).

In some embodiments, the electronic device establishes (308) a shared playback queue in accordance with a determination that the first user has obtained information for the shared playback session from the second user (e.g., David from Sara, as explained with reference to FIGS. 2A-2B). In some embodiments, the electronic device sends (310) the information for the shared playback session to the second electronic device of the second user (e.g., the server system establishes the code 206 and sends the code to Sara's host device). The first device of the first user obtains the information for the shared playback session from the second device of the second user. In some embodiments, the electronic device provides (312) the second device of the second user with user-selectable options to select how to provide the information for the shared playback session from the second device to the first device (e.g., the server provides sharing options to the client device as described in FIG. 2C). In some embodiments, the first device of the first user provides (314) information for the shared playback session to a third device (e.g., a third device of a third user). In some embodiments, any user of the media-providing service that has obtained the information for the shared playback session is enabled to share (316) the information with additional users of the media-providing service (e.g., David, a participant (not the host) is enabled to share the information for the shared playback session (code 206) with additional users). In some embodiments, only one device (e.g., a host device) is enabled to provide the information to the additional users of the media-providing service. In some embodiments, only the host device is enabled to control settings of the shared playback session (e.g., selection of the playback device, volume, identification of a media content item as a favorite, etc.).

In some embodiments, the electronic device receives (318), from the first device, a request to join the shared playback queue (e.g., the server receives, from David's device 102-2, a request to join Sara's session). In some embodiments, the request to join the shared playback queue is generated by device 102-2 in accordance with a determination that device 102-2 has received (e.g., scanned via a camera of device 102-2, detected via an audio transducer of device 102-2, received a PIN via a user input, and/or received a user input selecting a received link) a code (e.g., scannable code 206). In response to the request, the electronic device determines a device type of the first device and selects a joining method based on the device type. For example, in accordance with a determination that the device type is a desktop computer, the electronic device selects an audio code as the joining method (e.g., because a desktop may not have a camera to detect a scannable code), and in accordance with a determination that the device type is a mobile phone, a scannable code is selected as the joining method. In some embodiments, the electronic device transmits, using the selected joining method, the code to the client device. It is to be understood that different device types may require different joining methods. In some embodiments, the user of the device joining and/or hosting the session is enabled to select which joining method to use.

The electronic device provides (320) a shared playback queue to a first device of the first user and a second device of a second user, the shared playback queue including one or more media content items corresponding to a shared playback session. In some embodiments, the electronic device initiates (e.g., establishes) the shared playback session before providing the shared playback queue to the first device. In some embodiments, the electronic device initiates the shared playback session in response to receiving a user input at the first device of the first user and/or a user input at the second device of the second user. For example, the electronic device initiates the shared playback session (and the shared playback queue) in response to receiving an indication that the second user has scanned the sharing scan code presented on the first device of the first user (e.g., as described with reference to FIGS. 2A-2B). In some embodiments, the one or more media content items corresponding to the shared playback session are selected (e.g., added) to the shared playback queue by an input from the first user, an input from the second user, and/or automatically by the service provider.

In some embodiments, the electronic device provides (322) information corresponding to the shared playback queue (e.g., provides the media content items in the shared playback queue) to a presentation device (e.g., the presentation device selected from the list shown in FIG. 2A). In some embodiments, the shared playback queue is presented to (e.g., played back to) the first user and the second user at the presentation device. In some embodiments, both the first user and the second user are within a predefined geographic proximity to the presentation device (e.g., within a same room or household). In some embodiments, the electronic device (e.g., server) sends to the first device and the information is forwarded to the presentation device.

In some embodiments, the listening history corresponds to a first listening history and the electronic device stores (324), for the first user, the one or more media content items of the shared playback queue in a second listening history of the first user that is distinct from the first listening history. For example, the first listening history corresponds to a user's personal queue and a second listening history corresponds to the shared playback session the user has joined. In some embodiments, each distinct shared playback session corresponds to a distinct listening history. In some embodiments, all of the shared playback sessions the user has joined are stored in the second listening history of the user (e.g., the shared playback sessions are combined into the second listening history).

Referring to FIG. 3B, the electronic device identifies (326) a source of a first media content item of the one or more media content items in the shared playback queue. For example, the source of the first media content item corresponds to a user (or the provider) that added (e.g., selected) the first media content item to be included in the shared playback queue. In some embodiments, the electronic device identifies (328) the source as the first user in accordance with a determination that the first user selected the first media content item for addition to the shared playback queue (e.g., if David selects the content item to add to the shared playback queue, the server identifies David as the source of the selected content item). In some embodiments, the electronic device identifies (330) the source as the second user (e.g., Sara) in accordance with a determination that the second user selected the first media content item for addition to the shared playback queue.

Based on the identified source of the first media content item in the shared playback queue, the electronic device determines (332) whether to include the first media content item in the listening history of the first user. The electronic device is enabled to distinguish, of the content consumed by the first user, which content is selected by the first user, which content is selected by another user, and which content is selected by the media-providing service (e.g., generated or curated as a recommendation/playlist).

In some embodiments, in accordance with a determination that the first media content item is in the shared playback queue, the electronic device forgoes (334) including the first media content item in the listening history of the first user. For example, the electronic device is enabled to distinguish between content consumed during a user's personal playback session versus content consumed during a shared playback session the user has joined. In some embodiments, only the user's personal queue (consumed during the user's personal session(s)) is included in the listening history of the user.

In some embodiments, in accordance with a determination that the first user is the source of the first media content item, the electronic device includes (336) the first media content item in the listening history of the first user. In some embodiments, in accordance with a determination that the second user is the source of the first media content item, the electronic device forgoes (338) including the first media content item in the listening history of the first user. In some embodiments, in accordance with a determination that the first user did not select the first media content item (e.g., the second user or the content provider selected the first media content item), the electronic device forgoes (340) including the first media content item in the listening history of the first user. For example, within the shared playback queue, only media content items that were selected by the first user are included (e.g., tracked) in the listening history of the first user.

In some embodiments, the electronic device presents (342), to the first device of the first user, a user-selectable control to include shared playback queue items in the listening history of the first user. In some embodiments, the electronic device receives user input activating the user-selectable control. In response to activation of the user-selectable control, the electronic device includes the one or more media content items in the shared playback queue in the listening history of the user. For example, the user selects whether to include a shared playback session in their listening history (and affect the personalized recommendations/content for the user based on the shared playback sessions).

In some embodiments, the electronic device creates (344) a taste profile for the first user based on the listening history of the first user. For example, the taste profile is based on patterns identified based on the information stored in the listening history of the user. In some embodiments, the taste profile is assigned to the user (e.g., categorizes the user) as a profile representing genres, artists, or other characteristics of media content items that the user tends to consume. This allows the media-providing service to generate personalized recommendations for media content that match the taste profile of the user. The taste profile is generated and/or stored in taste profile module 528. In some embodiments, a second media content item is provided to the first device of the first user, and selection of the second media content item is based on the taste profile for the first user.

The electronic device provides (346) information for a second media content item to the first device of the first user based on the listening history of the first user. In some embodiments, the electronic device provides (e.g., streams) the second media content item to the first device for playback. In some embodiments, the information for the second media content item is provided to the first device after playback of the shared playback queue (e.g., after ending the shared playback session). In some embodiments, the information for the second media content item is provided to the first device during playback of the shared playback queue (e.g., while the shared playback session is ongoing). In some embodiments, the information for the second media content item is provided to the first device without user input (e.g., automatically) at the first device.

Although FIGS. 3A-3B illustrate a number of logical stages in a particular order, stages which are not order dependent may be reordered and other stages may be combined or broken out. Some reordering or other groupings not specifically mentioned will be apparent to those of ordinary skill in the art, so the ordering and groupings presented herein are not exhaustive. Moreover, it should be recognized that the stages could be implemented in hardware, firmware, software, or any combination thereof.
